 Title    Chemical Constituents of Cor chorus capsularis and C.olitorius (Jute Plant), Part IV* Isolation of Corosolic Acid, Ursolic Acid and corosin and Correlation of Corosin with Tormentic Acid  
 Abstract    Three triterpenoids have for the first time been isolated from fresh undried jute root, ursolic acid as its acetate, corosolic acid as its acetate and indicated to be urs-2a,2/?-diol-12-en-28-oic-acid and oxo-corosin isolated as its acetate-methyl-ester, C36H54O10, m.p. 160 °C, aD-15° (c 0.435%). The 24-carboxyl in corosin-anhydro-lactone-acetate has been reduced to the methyl group and the resultant lactone on acetylation indicated to be identical with tormentic acid lactone acetate.
